/var/run is problematic because its subdirectories are expected to
survive across reboots. I haven't tried /var/lock but there is no reason
for tmpfs not to work for this one.

Using a tmpfs for /var/tmp would definitely violate the FHS as it must
survive across reboots.

As for /tmp, this is the primary intended use for tmpfs and I use it
whenever possible. I don't know if it's a good idea when there isn't
much memory, though.
